Selection of Colour depth
By default, CATX DVI-D Switch Media/KVM Extender units transmit video with 18-bit
colours (=256K colours). You can also set up the units to transmit 24-bit (=16M colours).
Low colour depth enhances the number of frames transmitted per second, high colour depth
gives smooth colour grades.
